SPECIFICATION forming part of Letters Patent No. 763,402, dated June 28,1904;.

Application filed February 10, 1904. Serial No. 192,932. (No model.)

T 0 (LZZ whom, it may concern:

Be it known that I, EDWARD A. JOHNSTON, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Attachments for Mowing-Machines, of which the following is a complete specification.

This invention relates to side-delivery devices to be used in connectionwith mowingmachines when cutting grass or grain, the function of thedevice being to effect the delivery ofthe material out by the machineim' mediately in the rear thereof.

The purpose of this invention is to provide a simply-constructed andreadily-operated attachment that will enable the grain or grass to bedeposited in consecutive bunches 0r gavels in the rear of the machineand in a position that will not interfere with passing of the team ormachine in the succeeding round.

The improvement viewed otherwise may be regarded as a deviceto aid inthe manual discharge of the material out either in bunches or in swathin the rear of the machine or as means located in the rear of thecutting apparatus for imparting a diagonally rearward movement to thecut grain.

Further subordinate objects will appear in the disclosure of thisinvention, which has been embodied and illustrated in the accompanyingdrawings, in which Figure 1 is a plan view of a mower, showing theattachment forming the subject-matter of this invention in connectiontherewith. Fig. 2 is an enlarged plan of the attachment and the cuttingapparatus of the mower, the endless canvas or apron being removed tomore clearly present the construction of the frame of said attachment.Fig. 3 is a stubble-side elevation substantially of those parts shown inthe plan view of Fig. 2. Fig. 4 is a grain-side elevation of the cuttingapparatus with a portion of the platform connected therewith, showingthe method of supporting and adjusting the grainward end of the saidplatform and cutting apparatus. Fig. 5 is a detail, partly in section,showing the construction of the driving member connecting the drivingroller or drum of the attachment with the cross-shaft of the mower. Fig.6 is an 5 enlarged section of the conical driving-drum as indicated bythe line 6 6 of Fig. 2. Fig. 7 is a fragmentary View, partly in section,of the sectional roller at the receiving or upper end of the endlessconveyer. Fig. 8 is a frag- 5 5 mentary view of the frame of the mower,showing the location and method of supporting the supplementary seat.Fig. 9 is a rear elevation showing the caster-wheel which supports therear end of the platform and parts adjacent to the caster-wheel. Fig. 10is a section, as indicated by the line 10 10 of Fig. 1,

in which is shown the supporting means of the coupling-frame when in araised position. v Fig. 11 is a sectional view of the inner wall of theplatform, taken as indicated by the line 11 11 of Fig. 2, showing themanner of guiding the endless conveyer and the antifriction-rollers onthe ends of the slats of said conveyer. Fig. 12 is a section through theouter wall of the platform as indicated by the line 12 12 of Fig. 2.Fig. 13 is an enlarged detail in perspective, setting forth theconstruction of the antifriction-rollers on the slats of theendlessconveyer. Fig. 14 is a detail plan view showing the manner ofconnecting the frame of the platform to the finger-bar of the cuttingapparatus. Fig. 15 shows a mower with the improved attachment inconnection therewith, the cutting apparatus and attachment being shownin a folded position.

The attachment consists, essentially, of a frame on which is supported afixed table or platform for the initial reception of the grain 5 and aquadrantal-shaped endless conveyer immediately in the rear thereof.

The type of mower to which the attachment may be applied is notmaterial, and the one shown is of a common type, in which A is the 9main frame, and a and a the supporting and driving wheels therefor. B isthe tongue, C the operators seat, and C the supplemental seat for theattendant, who moves the cut grain, &c., back from the cutting apparatusD. E is the coupling-frame, and F the inner shoe. (6' is thecross-shaft, driven through the gear a and the pinion (0 to which thesaid shaft is secured. Further details of the several parts of the mowerare not regarded as material, since they in no wise affect the manner ofoperating the attachment.

The principal members of the frame of the attachment are the beam h,which forms the stubbleward side of the longitudinallyextending portionof the platform and constitutes the main supporting element, and thelong strip 7L, curved stubbleward at its rear end to meet the beam 7b,with which it is connected. The forward end of the beam h pivotallyconnects to a lug f on the shoe F by means of the strap if, and theforward end of the strip lb (see Fig. 14) forms a similar pivotalconnection with the finger-bar d by means of the strap if, engaging thearm cl, which is secured to the said finger-bar. The frame thus formedis made rigid by the diagonal braces 7:, is, and k while the strip h isstrengthened by the correspondingly-curved reinforcing-plate Zr, all ofwhich are clearly shown in Fig. 2.

Secured to the strip h is a sheet-iron plate forming the outer wall hfor a portion of the length of the receiving or primary platform and awall for the full length of the quadrantshaped frame of the endlessconveyer. Concentric with the outer wall it is the inner wall 7L5,secured to a strip 7L6, forming a construction similar to the said outerwall, with the addition, however, of the angle-irons h at the top andbottom which serveas guides for the endless apron. The width of thisquadrantshaped platform is shown to be somewhat less than the width ofthe primary platform; but this is merely by preference, as any width canbe given sufficient to enable'it to meet the requirements for which itwas designedviz., to convey the material from the primary platformdiagonally rearward and deposit it in the rear of the machine.

The outer end of the cutting apparatus and the platform-frame issupported by means of the grain-wheel F (see 4,) which journals on asuitable bearing on the lever f. This lever f is pivotally connected atits forward end to an upwardly-projecting lugf on the outer shoe F ofthe cutting apparatus and is provided with an aperture near its free endwhich is adapted to register with a series of apertures in the brace I.The bolt or pin f" secures the said lever f to the brace I in anydesired position. on the upward extension of the brace I is supportedthe rear end of the divider-board J, to which in turn is secured thesupplemental divider-board J.

Lying immediately in the rear of the cutting apparatus and between thewalls of the platform is the rectangular plate L, preferably of sheetmetal, and on this is first deposited the grain or grass after beingcut. Extending from the forward end of the quadrantshaped platform to apoint beneath the said plate L s the forwardly and rcarwardly adjustableplate L, strengthened by the rib Z on its forward edge. This plate Lterminates at its rear edge above the said quadrantshaped platform andin either side of said plate is the aperture Z, which can be made toregister with one of a number of apertures Z in the supports for saidplate. Small bolts engaging the apertures secure the plate L in thedesired position. L to be moved forward for the short grain and rearwardfor the long grain, as circumstances may require.

In suitable supports at the rear of the quadrant-shaped platform ismounted a conicalshaped drum M, driven by means of the universalextensible connection N, (see Figs. 1, 2, and 5,) connecting withthecross-shaft a, above referred to. This drum M is a conical frustumand consists, preferably, of a shaft on, to which are secured the largeand small circular heads on and m These heads m and 012. of diameterscorresponding to the relative lengths of the outer and inner walls ofthe platform, are provided with a series of notches in the peripheriesthereof, (see Fig. 6,) in which are secured the ends of the slats mconnecting the two heads. This construction will result in a drum whichis very light, and the slats will operate to give it a good grippingaction on the endless apron passing thereover.

M is a sectional roller located at the forward end of thequadrantal-shaped platform. This roller is comprised of a series ofcomparatively short sections in, the individual sections being ofsubstantially uniform diameter and free to rotate independently upon acommon shaft m". An endless conveyer 0, provided with a series of slats0, is thrown about the drum M and the sectional roller M, the canvasbeing made of a form to fit the plat form. With such an arrangementthere is a manifest tendency for the canvas to slip inward or toward thesmaller end of the drum M. The inner wall 7L5 serves as a guide to holdthe canvas to its proper course and prevent such movement. To reduce thefriction incident to the contact between the ends of the slats 0 and thewall 7f, antifriction-rollers 0 are placed on the ends of the slats, asshown in Figs. 11 and 13.

P is a casting which serves as a connecting means between the beam 71,,the rear wall of the platform h", and other parts. 7) p are two lugsprojecting rearward from the said casting P, as shown in Figs. 2, 3, and9. In these lugs are apertures in alinement with each other and on aline substantially transverse to the vertical axis of the caster-wheelQ. These apertures are adapted to receive the vertical axis 9 of thesaid caster-wheel when the platform is folded to a vertical position, sothat the wheel is thus made to serve as a support for the platform inboth normal working and folded positions. The support for the pivotalaxis 9 of the caster-wheel is This will enable the plate formed by theU-shaped bar 10, the arms of which are secured to the beam 72,, asindicated in Fig. 3.

S is the inside divider, extending rearwardly and terminating at a pointsubstantially above the junction of the beam k of the platformframe withthe inner wall if of the platform. The uprights s s, as shown in Fig. 3,pivotally connect with the frame of the platform, and the intermediateupright s extends downward and is secured to the wall I? by means of thebolt 8 thus rigidly securing the said divider in avertical position.When it is desired to fold the divider to a position indicated by thedotted lines in Fig. 1, the bolt 8 is removed, after which the dividerwill be free to be brought to a horizontal position ready for thefolding of the platform.

The supplemental seat C is mounted upon the supports 0 and is braced bymeans of the bar 0. (See Figs. 1 and 8.) Extending from the tongue B toa proper position in front of the seat 0 is a foot-support 0 To hold thecoupling-frame and inner shoe from the groundwhen the platformis raisedto a folding position, a rod 6, threaded at its upper end, is secured tothe coupling-frame E, as shown in Fig. 10. The rod 6 is adapted toengage an aperture in the plate I) on the tongue B. The'hand-nut e isthen turned, which causes the coupling-frame to be raised any desiredamount. When the platform is folded to a vertical position, the rod 2),which is connected by means of the eyebolt b to the tongue B, is made toengage the aperture (Z in the finger-bar d of the cutting apparatus andsustain it in this elevated position.

The operation of the device is obvious.-

WVhen in the opinion of the attendant a sufficient amount of grain orgrass has accumulated on the primary platform formed by the plates L andL, .he rakes it rearward until the bunch is engaged by thecontinuouslymoving endless apron O of the quadrantshaped conveyer. Thisapron conveys the bunch of cut material rearward and stubbleward,depositing it in the rear of the machine.
